(Sociedade Brasileira de Química, 2012-03)This work reports a systematic study of the structural and electrical behavior of three ternary phases of the TaxMo1-xS2 system (x = 0.55, 0.75 and 0.90) and their intercalation compounds resulting from both chemical and ...
-
(Elsevier, 2013)This paper discusses a well-represented fossil record of cartilaginous fishes (Chondrichthyes) from southern South America. The recovered samples allow the recognition of three assemblages with chronostratigraphic and ...

(MUNKSGAARD INT PUBL LTD., 1997-05-15)The structure of the title diterpene, C20H34O3 (8 alpha,13R-epoxylabd-14-ene-1 alpha,5 alpha-diol), exhibits a very uncommon oxidation pattern, with two axially disposed hydroxyl substituents at C1 and C5, and five tertiary ...
-
(FEBS, 1999)Acyl-CoAs are present at high concentrations within the cell, yet are strongly buffered by specific binding proteins in order to maintain a low intracellular unbound acyl-CoA concentration, compatible with their metabolic ...
-
(American Physical Society, 2013)We investigate mobility regimes for localized modes in the discrete nonlinear Schr¨odinger (DNLS) equation with the cubic-quintic on-site terms. Using the variational approximation, the largest soliton’s total power admitting ...
-
(The Linnean Society of London, 2013)Direct development and water dependence entail limited vagility in freshwater fauna. In these organisms, the population structure is probably linked to restrictions imposed by the habitat. In this study we investigate ...
-
(American Chemical Society, 2002-11)A new norditerpenoid, yaretol (1), was isolated from the whole plant of Azorella madreporica. The structure of 1 was established by one- and two-dimensional NMR techniques and confirmed by X-ray diffraction analysis.
-
(ACADEMIC PRESS INC., 2013-02)A new family of Cu2Mn1-xCoxSnS4 chalcogenides has been synthesized by conventional solid-state reactions at 850 degrees C. The reactions products were characterized by powder X-ray diffraction (XRD), energy-dispersive X-ray ...
-
(Springer, 2013)Background: The Mediterranean zone of central Chile (30° to 38°S) is one of the 25 diversity hotspots in the world. However, there are few phylogeographic studies which identify the factors that have influenced ...
-
(Springer, 2013)It has been suggested that a respiratory stress is part of the mechanism through which the dormancy-breaking compounds, hydrogen cyanamide (HC) and sodium azide, induce the release of buds from the endodormancy (ED) ...
-
(2013)The Wnt signaling pathway plays important roles during different stages of neuronal development, including neuronal polarization and dendritic and axonal outgrowth. However, little is known about the identity of the ...
-
(American Chemical Society, 2013)This work reports on studies of two-dimensional networks of Cu2+ ions, built by exchanging Na-bentonite with Cu2+ aqueous or with the bis(ethylenediamine) complex, [Cu(C2H4 (NH2))2]2+, at different concentrations of the ...
-
(CAMBRIDGE UNIV PRESS, 2009-06)Avian Plasmodium and Haemoproteus parasites are easily detected by DNA analyses of infected samples but only correctly assigned to each genus by sequencing and use of a phylogenetic approach. Here, we present a restriction ...
-
(Wiley Periodicals, 2013)Triblock copolymers with surface-active properties, referred to as Pluronic, have shown potential medical applications such as drug delivery to selective targets in the human body. In particular, the transport of ...
-
(PERGAMON-ELSEVIER SCIENCE, 2002-04)The Al0.21Mn0.78PS3, Al0.15Cd0.83PS3, In0.20Cd0.70PS3 and Ga0.28Cd0.58PS3 compounds have been synthesized by the cation-exchange process used for other cationic species of the same family. These compounds were characterized ...
-
(British Ecological Society, 2013)1. Forest fragmentation may intensify recruitment limitation through impacts on seed production, dissemination and seedling establishment processes. In an ancient mosaic of fog-dependent rain forest patches on coastal ...
